Final answer:
The correct answer is C) Continuity Equation. The equation of continuity is a fundamental principle in fluid mechanics that states that the flow rate of an incompressible fluid must remain constant along a streamline.
Step-by-step explanation:
The correct answer to the question is C) Continuity Equation.
The equation of continuity is a fundamental principle in fluid mechanics that states that the flow rate of an incompressible fluid must remain constant along a streamline. In other words, the mass flowing into a pipe or tube must equal the mass flowing out. The equation of continuity is expressed as:
A1v1 = A2v2
Where A1 and A2 are the cross-sectional areas of the pipe or tube at different points, and v1 and v2 are the velocities of the fluid at those points.
